  • 摘要: 加速器驱动次临界装置(ADS)对加速器运行稳定性和失束指标提出了前所未有的要求。对于超导直线加速器的研究发现,超导腔失效是失束的一个较大的来源,故针对超导腔的失效情况,本文提出分段补偿新方法,以提高高功率超导直线加速器的运行稳定性。提出的分段补偿方法与已有的全局补偿和局部补偿的方法相比,在保证加速器出口束流品质与无束损束流传输的同时,分段补偿束流能量,优化了参与能量补偿的超导腔数量,降低超导腔的备份功率源需求。论文最后针对CiADS的超导直线加速器的物理设计,做了分段补偿的多粒子模拟。结果表明,采用了分段补偿方法实现超导腔失效补偿的前提下,参与补偿过程中改变腔压的超导腔数量比例为48%,对功率源总的功率备份冗余需求小于20%。


    The accelerator driven subcritical system (ADS) has put forward unprecedented demands on the stability and beam trip of the accelerator operation. Depending on analysis, failure of the superconducting cavities is a major cause for beam trip of the superconducting cavity. Therefore, a new method of piecewise compensation is proposed to improve the stability of high power superconductivity linac. The piecewise compensation scheme proposed in this paper is compared with the existing global compensation and local compensation technology. While guaranteeing the beam quality of the accelerator and without beam loss transmission, the piecewise compensation method can optimize the number of superconducting cavities involved in energy compensation and reduce the demand for the backup redundancy of power sources of the superconducting cavities. At the end of the paper, the multi-particle simulation of piecewise compensation aims at the physical design of CiADS superconducting linac. The result shows that 48% of superconducting cavities modify the cavity's Epeak during the compensation process and the demanded redundancy of total power sources is less than 20% under the premise of successful compensation for the failure of superconducting cavities through the piecewise compensation method.
